[Openal-devel] AL_REFERENCE_DISTANCE Question

I'm a bit confused about the usage of AL_REFERENCE_DISTANCE.
In the Programmer's Guide it states that:
AL_REFERENCE_DISTANCE f, fv, i, iv the distance under which the volume
for the source would normally drop by half (before being influenced
by rolloff factor or AL_MAX_DISTANCE)
However, in the Specification it says that:
1. Distance attenuation is calculated first, including minimum
(AL_REFERENCE_DISTANCE) and maximum (AL_MAX_DISTANCE) thresholds.
I'm confused about AL_REFERENCE_DISTANCE. What exactly is it doing?
Is it a threshold value or something else.
In my demo program it defaults to a value of 1.0. Is that correct?
